Soluble amyloid oligomers may injure cholinergic terminals via CHRNA7-linked calcium dysregulation, making cholinergic dysfunction an early downstream readout of amyloid toxicity. This remains mechanistically plausible but is not a strong lead translational thesis.
AD-risk trafficking defects in SORL1/BIN1/PICALM/retromer may generate parallel early outputs: amyloidogenic APP sorting and selective basal-forebrain cholinergic trophic failure. This best fits the debate because it explains why temporal order can appear inconsistent across cohorts without requiring a single linear sequence.
Convergent vs Divergent Predictions
This summary checks where the selected hypotheses point toward the same target or mechanism, and where they pull in opposite directions.
APP recurs across 2 selected hypotheses with aligned directionality in autophagy lysosome, synaptic circuit dysfunction.
Divergent signals
No direct polarity conflicts detected among the selected hypotheses.
